Scientists at Purdue University have created the world’s whitest paint. The paint is so white it could reduce and/or eliminate the usage of air conditioning.
Why did scientists invent such a paint? It’s to curb global warming.
Researchers said the idea was to make a paint color that would bounce sunlight away from a building.
According to Purdue University, the paint reflects almost 98% of solar radiation. Because the paint absorbs less heat, a surface coated with this type of paint is cooled below the surrounding temperature without electricity.
This is the whitest paint on Earth and it could eliminate need for air conditioning https://t.co/DefsA0gBXS— 13News Now (@13NewsNow) September 17, 2021
Two features make this paint ultra-white: a very high concentration of a chemical compound called barium sulfate – also used in photo paper and cosmetics – and different particle sizes of barium sulfate in the paint, scientists at Purdue said.
According to a news release, researchers at Purdue have partnered with a company to put this ultra-white paint on the market.
